Central Tube Light Armoured Fiber Optic Cable

The structure of the GYXS/GYXTW fiber optic cable is that a 250μm optical fiber is sleeved into a loose tube made of high-modulus material, and the loose tube is filled with a waterproof compound. The loose tube is covered with a layer of double-sided plastic-coated steel tape (PSP) longitudinally, and a water-blocking material is added between the steel belt and the loose tube to ensure the compactness and longitudinal water blocking of the optical cable.

Description

Product standards

YOFC’s GYXS/GYXTW fiber optic cable complies with YD/T 769 standard.

Features:

• Very good mechanical and temperature properties

• The loose tube material itself has good hydrolysis resistance and high strength

• The tube is filled with special paste to protect the optical fiber

• Good compression resistance and softness

• Double-sided plastic-coated steel tape (PSP) improves the moisture permeability of fiber optic cables

• Two parallel steel wires ensure the tensile strength of the fiber optic cable

• Small diameter, light weight, easy to lay

• Long delivery lengths
